ATMSpeed/155 Module Ports and Connectivity
ATMSpeed/155 module ports have the following features:
• 155 megabit per second (Mb/s) full-duplex OC-3 ATM ports on each module
• Onboard connectors
— The ATMSpeed/155 switch module (two-port and four-port versions)
offers multimode fiber support with SC connectors.
— The ATMSpeed/155S switch module offers single-mode fiber support
with SC connectors.
— The ATMSpeed/155 MCP switch module offers multimode fiber with SC
connectors. It also offers one serial port with a Mini DIN 8 connector and
one 10BASE-T port (configured as MDI-X) with an RJ-45 connector for
network management.
— The ATMSpeed/155 MDA and ATMSpeed/155 MDA MCP switch
modules offer field installable two-port MDAs for MMF, SMF, and UTP
connectivity. The ATMSpeed/155 MDA MCP module also offers one
serial port with a Mini DIN 8 connector and one 10BASE-T port
(configured as MDI-X) with an RJ-45 connector for network
management.
• Per-port features
— LEDs to indicate operational status of each port
— Wirespeed port-to-port switching for local traffic without using any ATM
backplane bandwidth
